impedance manometry

Impedance manometry is a diagnostic technique used to evaluate how well the esophagus (the tube that carries food from the mouth to the stomach) functions. It combines two measurements: pressure sensing (manometry) to assess muscle contractions, and impedance testing to detect the movement of liquids and gases during swallowing. This helps doctors understand if the esophagus is pushing food properly and if the swallowing process is coordinated. Impedance manometry provides detailed information about esophageal motility and the presence of reflux, aiding in the diagnosis of swallowing disorders and reflux issues.
